Hi,
Noted your history of very mild
chest pain and pain in left arm.
As advised by your Doctor, please get the EKG/ECG and other cardiac evaluation like
Echocardiography to rule out issues related to heart.
If the cardiac check up is normal also get the pulmonary check up.
Each for the movements of the upper limbs that increase the discomfort.
If all the investigations are within normal limits then this may be a condition called
Costochondritis.
Relax and avoid stress and
anxiety.
Avoid people with viral infections.
Take an anti-inflammatory medications and oral
steroid if required.
Local Rubefacient liniment.
All these things done step by step should give you the best possible diagnosis and thus plan for management.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
